Title: Improvements in or relating to polyamide compositions
IPC: C08G69/00
Filed: 1942-04-01
Abstract: Polyamide compositions are prepared by heating at temperatures above 180 DEG  C., but below the decomposition temperature, until homogeneity is obtained, a melt comprising a synthetic linear polyamide wherein the majority of the amido groups are secondary and which has an intrinsic viscosity of at least 0.4, and at least one further synthetic linear polyamide in which at least 50 per cent of the amido groups are tertiary, the lateral substituents on its amido nitrogens being hydrocarbon groups attached to the nitrogens through aliphatic carbon atoms, and which has an intrinsic viscosity of at least 0.2, the polyamides being blended in such proportions that from 1 per cent to 50 per cent of the amido groups in the resulting composition are tertiary.  The tertiary amido polyamides appear to function as plasticizers for the secondary amido polyamides. Homogeneity is generally reached in a period of from 5 to 60 minutes after complete fusion has been effected, and some amide interchange probably takes place during heating.  Many starting polyamides are specified, and examples are given of the preparation of blends from: (1) poly-N : N1-dimethylhexamethylene adipamide and polyhexamethylene sebacamide; (2) poly - N : N1 - diethylhexamethylene adipamide and the interpolymerization product of hexamethylenediammonium adipate, hexamethylenediammonium sebacate, and epsilon-aminocaproloctam; and (3) polyhexamethylene adipamide and the interpolymerization product of N : N1 - dimethylhexamethylenediammonium adipate and hexamethylenediammonium adipate.  The products can be formed into fibres, films, or other articles, and they exhibit improved receptivity for many dyestuffs.

Title: Method of hardening cutting tools
Inventor: ANDERSON WILLIAM THEODORE
IPC: C21D9/24
Filed: 1957-02-13
Abstract: In a method of hardening a cutting tool made entirely of high speed tool steel, the formed tool is subjected to two successive heating stages in which (1) the tool is uniformly heated across its width to a temperature at which a selected less-than-maximum hardness is attained and (2) the cutting edge portion only is heated to such a temperature that maximum hardness is obtained in the cutting edge portion, the second heating occuring while the entire tool is at substantially the temperature it possesses on leaving the first stage.  The heating stages are preferably carried out so that the hardness is initially 45 Rockwell C and the later maximum hardness attained is 65 Rockwell C.  The temperatures in the two stages are then 1697 DEG F. and 2255 DEG F. respectively.  Before hardening a saw blade the teeth are preferably formed, and if desired set.  After cooling, preferably by standing in still air at room temperature for within one to two hours with a saw band, the tool is tempered.  In an example, pinpointed flames issuing from two rows of nozzles on opposite sides of the path of a saw band and positioned to impinge only on the tips of the passing teeth are employed in the second stage.  Examples of high speed tool steel given have the following compositions: carbon 0.79-0.86 per cent, manganese 0.35 per cent (max.), silicon 0.40 per cent (max.), chromium 3.90-4.40 per cent, molybdenum 4.75-5.25 per cent, vanadium 1.75-2.05 per cent, tungsten 6.00-6.75 per cent, phosphorus 0.03 per cent (max.), sulphur 0.03 per cent (max.), iron balance; or, carbon 0.70 per cent, manganese 0.3 per cent, silicon 0.25 per cent, chromium 4.0 per cent, vanadium 1.0 per cent, tungsten 18.0 per cent, iron balance.
